Special Events: Areas within the park, such as the GP Track
(Grand Prix Motorcycle Track) and Area 5 (Large Private Group
Camping Area), can be reserved for special events. Over 100
special events take place annually in these special use areas
including regional and national motorcycle races (Motocross
and Cross Country/Hare Scrambles), 4x4 poker runs, guided
trail rides, and 4x4 obstacle course challenges. Over 16,000
visitors attend special events held at the park each year. Other
events that draw visitors to the special event areas include
everything from weddings to club outings, group camping, and
vehicle manufacturer product release events.
The Lower Ranch: The Lower Ranch area is set aside for dirt bike and ATV use on more
than 128 miles of trails. The Lower Ranch consists of three distinct areas: Granitic, Adobe,
and Renz. The trails in all areas are mostly one way and are designated by difficulty rating.
The Granitic Area is characterized by steep hills, sandy soil, and dense chaparral
vegetation. This area offers year-round riding with excellent traction in the winter months.
Most of the trails in this area are wide enough to accommodate ATVs with the exception of
a few single tracks that are for dirt bikes only.
The Adobe Area is characterized by rolling hills, clay soil, and a mix of grassland and oak
woodlands. This area is popular among both ATV and dirt bike riders. There are several
hill climbs of varying difficulty and a mix of
narrower ATV trails and single track. Due to
the soil in this area, wet weather closures
frequently occur throughout the rainy
season.
The Renz Area has become very popular
among dirt bike riders and consists of 22
miles of single track trails. The trails were
designed using state-of-the-art techniques
to limit erosion, sound, and noise from OHV
activities while maintaining rider interest.
This area consists of clay based soil and
is subject to frequent wet weather closures
throughout the year.
Additional OHV opportunities in the Lower
Ranch include a variety of tracks and open
Campground Infrastructure and
Rehabilitation Project
In the fall of 2014, work began on
the Campground Infrastructure and
Rehabilitation Project. The scope of work
focused on rehabilitating infrastructure
in three campgrounds to bring them to
a consistent level of service and replace
ageing utilities. Work consisted of upgrading
water systems, adding combo buildings
with showers and flushing toilets, electrical
and sewer upgrades, replacing campsite
furnishings, improving vehicle circulation,
correcting drainage, and providing amenities
like Wi-Fi. The project was completed in the
summer of 2015.
